i everyone,
I'm using platform N01 with a spi flash running OTA code. However I found an issue when burning image on to external flash.
I found that sometimes I need to erase whole chip before I could successfully download images to external flash...
I've checked the code, it appears that it will give erase sector command before every write. Ideally this should work, however I keep seeing "Verify error - Data was not written successfully - abort!" as below
Received command: POST_WRITE_VERIFY WRTIE_ERASE_IF_NEEDED
Destination address: 126976
Size: 16384
Initialising
Done initialising
Verifying existing data!
Verifying after write
Verify error - Data was not written successfully - abort!
I could download code after given this command:
.\tools\OpenOCD\Win32\openocd-all-brcm-libftdi.exe -f ./tools/OpenOCD/BCM9WCD1EVAL1.cfg -f ./tools/OpenOCD/stm32f2x.cfg -f apps/waf/sflash_write/sflash_write.tcl -c "sflash_erase SSBWMN01 0" -c shutdown
My project is using spansion flash, does anyone know how to solve this issue?
It's pretty inconvenient that I have to manually give command every time I need to update code.
